To all whom it may concern:

Be it known that I, BALDWIN S. BREDELL, a citizen of the United States,residing at Camden, in the county of Camden and State of New Jersey,have invented certain new and useful Improvements in Transferring-Presses, of which the following is a specification.

My invention relates to improvements in tra sferring presses, the objectof the invention being to provide an improved press of this characterwhich will cut or stamp into a plate, a single letter or character ateach operation of the press.

A further object is to provide improved means for imparting a slightrolling action to the transferring wheel, when the latter is presseddown upon the plate, upon which the transfer is made, so as to cut thecharacter sharply into the plate.

A further object is to provide an improved transferring wheel withimproved means for centering the several characters around the peripherythereof, with relation to the plate upon which the transfer is made, andprovide improved means for releasing said centering means when pressureis applied upon the roll to imprint the character in the plate, andpermit the wheel a slight rolling movement to clearly cut the characterinto the plate.

A further object isto provide improved means for mounting the transferwheel improved means for adjusting the wheel laterally so as to properlyposition it relative to the plate, and provide improved means for movingthe Wheel mounting, vertically, and backward and forwardly.

A further object is to provide an improved mounting for the transferringwheel, which enables a wheel to be readily removed and replaced byanother, and which permits the wheel to be readily turned to bring anyof its characters into operative position.

A further object is to provide in combination with the improvedtransferring wheel and its mounting, an adjustable sup port for theplate upon which the transfer is made, which enables the plate to beclamped thereon and moved with great pre cision and accuracy, so as toposition the plate to receive the characters from the wheel.

A further object is to provide an improved transferring press, whichwill greatly reduce the cost of transferring upon ordinary Specificationof Letters Patent.

plates,-not only plates for cards, but for practically all similarmatter in which individual characters are used, which will greatlyreduce the cost of transferring, and which may be operated by anyworkman of ordinary intelligence, not requiring skilled labor, and whichwill do the work rapidly, neatly, and more uniformly than can beaccomplished by hand transferring.

A further object is to provide an improved transferring press, which iscapable of a Wide range of utility in the manufacture of transferringplates, which is of extremely simple inexpensive construction, strongand durable, and not liable to become broken or injured in use, butwhich can be easily and quickly repaired should any of the parts he comedamaged.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings; Figure 1, is a View in front elevationillustrating my improvements. Fig. 2, is a view in vertical crosssection taken at one side of the wheel mounting. Fig. 3, is an enlargedfragmentary view in front elevation of the wheel mounting showing thetransferring plate support in section. Fig. l, is aview in sideelevation of Fig. 8. Fig. 5, is a bottom view of Fig. 8. Fig. 6, is anenlarged plan view of the plate support adjusting mechanism. Fig. 7, isa view in section on the line 77 of Fig. 6. Fig. 8, is a View in sideelevation of one transferring wheel. Fig. 9, is a view in frontelevation thereof. Fig. 10, is a view in side elevation of the oppositeside to that shown in Fig. 8, and Figs. 11 and 12, are views in end andside elevation of the screw for adjusting the wheel laterally in itsmounting.

1 represents a table supported on suitable legs 2 and provided at eachend with uprights or standards 3, secured to the table and supporting attheir upper ends a shaft 4: extending longitudinally of the table andabove approximately the center thereof.

Two rearwardly projecting crank arms 5 are fixed to the shaft 4:, andspaced apart at opposite sides of the center of the press, and areconnected by a pin 6 on which a hanger 7 is pivotally supported anddepends in a substantially vertical line therefrom. This hanger 7comprises two side bars 8, 8, with a connecting plate 9 between them andfixed thereto. The bars 8 extend below the plate 9 and at their lowerends are made with rearwardly projecting feet 10, which are pivotallyconnected by a link 11 with crank arms 12 on a shaft 13. This shaft 13is mounted in the rear ends of extensions 14 on standards 3, and hassecured on one end a large segmental hand wheel 15, the movement ofwhich in one direction being limited by a lug 16 on one end of table 1and lo cated in the path of movement of one of the spokes 17 on saidhand wheel. This segmental hand wheel is preferably located at the righthand end of the press, while at the left hand end of the press a lever18 is fixed to shaft 4, so that the operator with his right handmanipulates the hand wheel 15, and with his left hand, lever 18, themovement of the latter in one direction be ing limited by one of thelegs 2.

The lower edges of the bars 8 of hanger 7 are made with curved recesses19 forming bearings for the trunnions 20 of my improved transferringwheel 21, and the trunnions 20 are normally held in the bearings 19 bymeans of a vertically movable frame 22. This frame 22 comprises twovertical bars 23, 23, which are positioned against the front faces ofbars 8, and are provided with longitudinal slots 24. In these slotsguide blocks 25 of general T-shape in cross section are positioned, andsecured to bars 8 by screws 26, permitting free vertical movement of thebars 23, but the enlarged outer ends of the blocks 25 prevent any escapefrom bars 8. These bars 23 are connected by a plate 27 which compelsthem to move together, and the two bars 23 and this plate 27 constitutethe vertically adjustable frame 22 above referred to. The lower portionsof the bars 23 are off set as illustrated at 28 and at their extremelower ends project rearwardly and are provided with inwardly projectingfingers 29, which engage under the trunnions 20 and hold them up in thebearings 19. This frame 22 is normally held in 7 its upward position bymeans of two coiled springs 30 fixed at one end to plate 27 and at theirother end to the plate 9 of hanger 7. These springs 30 draw the frame 22upwardly and hold plate 27 in engagement with a cam 31, the latterhaving rotary mounting on a pin 32 fixed to plate 9, and the upper edgeof plate 27 engages in a recess or flat portion of the cam 31. An arm 33is fixed to'the cam and adapted to permit its turning to force the frame22 downwardly when it is desired to remove a transferring wheel, andthis movement of the cam is limited by a crank pin 34 projecting out--ward from the cam and adapted to engage a pin or lug 35 fixed to theplate 27.

A somewhat bowed spring 36 is secured to the right hand bar 8 of hanger7, and at its lower free end engages the right hand trunnion 20 of thetransferring wheel 21, its lateral pressure, however, being limited by ablock 37 fixed to bar 8. Against the left hand trunnion 20 of thetransferring wheel, an improved adjusting screw 38 bears. This screw ismounted in a bracket 39 secured by screws 42 to the left hand bar 8 andthis bracket, or rather the lateral extension 40 thereof, is preferablysplit: or bifurcated and it is in this split or bifurcated portion thatthe screw threads which are engaged by the threads of screw 38 arelocated. A suitable set screw 41 connecting the two members of thebifurcated extension, serves to clamp with suliicicnt force against thescrew 38 to insure a uniform movement, or in other words, prevents anywabbling of the screw when once adjusted.

On the outer end of screw 38, a milled head or finger hold 43 isprovided and a disk 44 is also fixed to the screw 1 and is preferably anintegral part of the finger hold 43. This disk 44 is provided with acircular series of notches 45, and around the enlarged. head back ofthis disk 40, numerals in a regular scale are located.

46 is a locking dog which is pivoted to the extension 40 by means of apin 47, and has a finger hold 48 on its free end. This dog 46 is adaptedto engage in any of the notches in the disk 44, so as to lock the screw38 at any adjust-ment.

lVhile my improvement is in no wise limited to the particular number ofnotches in this disk 44, I preferably make forty notches and number eachalternate notch, beginning with Zero and numbering each alternate notchat each side of the zero mark from one to ten so that the head of thescrew may be adjusted either right or left a distance equal to wholenumbers or half numbers and a lateral adjustment of the transferringwheel may be had with great accuracy.

The transferring wheel preferably coinprises a removable ring 49 whichis clamped between a fixed head 50 and a clamping ring or nut 51,screwed onto a threaded portion 52 of the casting forming the twotrunnions 20 and the head 50. This nut or ring 51 is provided withnotches to receive a spanner wrench or an ordinary pin for turning thesame, and the ring 49 is provided around its periphery with raisedcharacters constituting dies which are to be forced into the plate to betransferred, and while the left hand face of the ring containscharacters corresponding with the characters on the periphery of thewheel so as to enable the operator to readily position the wheel for anycharacter, the right hand. side of the ring 49 is provided with notchesor grooves 54 corresponding with the characters on the periphery andwith these notches or grooves 54, a spring pressed pin 55 engages so asto hold the wheel against accidental movement. This pin 55 has asharpened end to engage in the notches or grooves 54:, and is secured ina swinging arm 56, the latter mounted upon a hinge pin 57, supported insuitable bearings 58 on the foot 10 of the right hand bar 8, and acoiled spring 59 is located on this hinge pin 57 and has one endbearing.

against the arm 56, to press the arm inward toward the transferringwheel, and hold the pin 55 in engagement therewith.

The arm 56 is provided with a finger 60 which is located in the path ofmovement of a lug 61, projecting downward from the right hand bar 23,said lug having a beveled or cam face to engage the finger 60 and drawthe pin 55 away from the transferring wheel, to permit the latter toturn, as will more fully hereinafter appear.

A shaft (32 is fixed in standard 3, and on this shaft 62, forwardly anddownwardly projecting arms 63 are fixed. The free ends of these arms 63are located beside or spaced from the bars 8 of hangers 7 and are provided with screw threaded sleeves 64 in which adjusting screws 65 aremounted. The inner ends of these screws are concaved and engage balls 66which are located in curved sockets in disks 67, said disks positionedagainst the bars 8 of hanger 7. The outer ends of these screws areprovided with spanner wrench receiving heads (38 to permit theiradjustment, so that the hanger, or in fact the entire transferring wheelmounting, may be adjusted laterally so .as to produce the best results,and the movement of the transferring wheel mounting vertically by meansof the shaft 4 and crank arms 5, and forward and rearward by means ofthe shaft 13 and crank arms 12, is guided by means of these screws 65,balls 66 and disks 67, as the bars 8 move between the disks.

1 would have it understood that by use of the term transferring wheelmounting I mean this term to cover the hanger 7 and the parts supportedthereby as distinguished from the other parts of the press. Below thistransferring wheel mounting is an adj ustable transferring plate support69 which is of general semi cylindrical form having its upper flat facepositioned below the transferring wheel and its lower curved facesupported in a block 70, the latter concaved to receive the same andmade hollow. This support 69 is adjusted on its axis by means of screws71 and is moved longitudinally by means of a screw threaded rod 72, butas the particular construction of this support and its connection withblock forms no part of the present invention, it is not necessary todescribe the same in detail, except the means for turning the rod 72 theexact distance, which will be hereinafter explained.

The upper face of the support is provided with longitudinal grooves 7 3in which plate engaging clamps 7d are mounted and by means of saidclamps, the plate illustrated at 75, may be rigidly secured on support69. Theouter end of the rod 72 projects through a bearing 76 and aratchet wheel 77 is secured on the rod 72 against the outer face ofbearing 76. 011 the outer end of rod 72, a cup 78 is mounted to turn,and is provided with a crank arm 79 to turn the same. In this cup a pawl80 is pivotally mounted and is held in engagement with the ratchet wheel77 by means of a spring 81 secured in the cup, and the cup is held inposition on the end of a rod by means of a headed screw 82 screwed intoa threaded socket in the end of the rod. The outer face of the cup 78 isprovided with a scale which registers with a point on hearing 7 6 sothat when the crank arm 79 is turned, the scale will register the lengthof movement imparted to the support 69 by the screw threaded rod 72 andthe pawl 80 will, upon the return movement of the arm, ride over theratchet teeth without turning the rod.

In connection with my improved press, I employ certain charts which givethe accurate measurement as accorded by this rod 72 for the movementofthe support in accordance with the style of characters on the transferwheel, so that the type may be spaced with absolute accuracy, but thesecharts form no part of the present invention, and are thus brieflyreferred to so that it may be understood how applicant obtains anabsolutely accurate positioning of the plate below the transferringwheel to receive the several characters thereon.

When a line has been transferred on the plate, the cup 78 and the rod 72are locked together by means of a suitable pin inserted through openings83 in the cup and rod, when by turning crank 79, the support 69 may bereturned to normal position.

The operation is as follows: When a plate upon which the transfer is tobe made has been secured on support 59 by the clamp 74, rod 72 is turnedby means of crank arm 79 to position the plate to receive itsfirstcharacter. The operator then with his hand, turns the transferwheel 21 until he brings the character desired to the lowest point ofthe wheel. He then draws lever 18 outwardly which, through the medium ofshaft 4 and crank arms 5, forces the wheel mounting downwardly to pressthe transferring wheel 21 down upon the transferring plate 75,imprinting the character into the plate. This downward movement of thewheel mounting'causes the beveled lug 61 to engage the fmger 60, andmove the pin laterally to free the same from engagement with its notchor groove 54.- in the transferring wheel. The operator then imparts tothe segmental hand wheel 15, a slight oscillating movement, which,through the medium of shaft 13, crank arms 12, and link 11, the wheelmounting is given an oscillating movement pivoting the same upon the pin6. This causes the transferring wheel, while being pressed down on theplate, to roll slightly back and forth thereby cutting the charactersharply into the plate. Ihe op erator then moves lever 16 and thesegmental hand wheel 15 back to normal posi tion, which causes the wheelmounting and the wheel to be elevated. He then, by means of the crank79, adjusts the support 69 to position the plate 7 5 for the nextcharacter. He then turns the transferring wheel to bring the nextcharacter desired to the lowest point of the wheel, and this operationis repeated until the plate upon which the transfer has been made iscompleted.

A different style of type is on the difierent wheels, and should adifferent style of type be desired on the same plate the operator swingsthe lever 35 to one side pressing down the frame 22, when he can liftthe transferring wheel out of its mounting and place a. new one therein,and it frequently happens in transferring that a number of these wheelscontaining different styles of characters are necessary to make theplate.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
